SHUTTLE.

nosaero.

To aZZ whom it may concern Be it known that I, Francesco RENzo, a subject of the King of Italy, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Shuttles, of which the following is a specification.

This invention relates to shuttles of that class having means to carry the filling package which is adapted to releasably hold said package thereon, that is, so that when the said means is in working position said package will be held against movement thereon but when elevated will allow the removal therefrom or application thereto of said package unobstructed.

In the accompanying drawing, Figure 1 is a plan of the improved shuttle; Fig. 2 is a longitudinal sectional view of the same, the filling package being shown in position; Fig. 3 is a view similar to Fig. 2 with the package removed, this figure also showing in dotted outline the spindle in the elevated position and (in full lines) the package partly in troduced onto the same; and, Fig. 4 is a sectional view on line wm of Fig. 2.

The shuttle body a having the open cavity 6 for the filling package 0, together with its spindle d pivoted at its butt on the trans verse pin 6 so that it may be swung from the housed position thereof shown in Figs. 2 and 3 to the projecting position indicated by dotted lines in Fig. 3, and the usual bent leaf spring fiheld in contact with the angular surface of the spindle butt by the pins g g and adapted thus to hold the spindle either in its housed or projecting position, are or may be, excepting as hereinafter indicated, all substantially the same as in ordinary shuttles.

On a pin it parallel with the pin 6 and traversing the usual rearward extension 71 of the shuttle cavity is fitted the coil y of a gripping member 7a in the form of a wire spring, one (the shorter) end Z of which is bent downwardly and bears against the curved surface Z of the butt of the spindle behind its axis (pin 6) and at one side of a groove 9 hereafter referred to and the other end portion of which projects generally substantially in the same direction as the spindle, having a downward bend it near the coil and then extending in a long upward curve, as at 0, and finally having its extremity rebent to form a curved portion 20, convex to the portion 0. From its butt-end to Specification of Letters Patent.

a suitable point forward the upper or relatively outer side of the spindle has a groove 9, the bottom of which affords a bearing surface on which the portion 29 of the member it rests, said surface being deflected away from the member 70 at the point r, as by deepening the groove 9 in forming it, say by using a circular saw, or the like. The forwardly projecting portion of the member 70 has contact with the bottom of the groove, as shown,

at the bend a and the extremity 10. It normally tends to stand in the position shown in Fig. 3 (full lines), so that if a snugly fitting cylinder, such as a cop tube .9, has been slipped over the spindle and made to embrace the forwardly projecting portion of member k, the part 0 of the latter will assume an arched form and so exert frictional pressure against the bore of the tube and serve to hold the tube thereon. The grip of the spindle and member on the tube may be enhanced by the usual spurs 6 formed on the spindle.

The relative position of the spindle and the forwardly projecting pOI'tiOn of member 70 in the raised position of the latter is indicated in the dotted outline of these parts in Fig. 8, in which the said portion of member 70 is seen to have receded more or less into the spindle. This condition is due to the differential movements of these parts about their fulcra and h in elevating them, (it being understood, however, that the pivotal movement of said portion of member 70 is incident to the bending of said member around the pin it which, with the curved face Z of the spindle, holds the end portion Z of said member substantially stationary at this time,) resulting in the present instance in the projecting portion of member 7a traveling (relatively) toward the free end of the spindle, and being allowed, as it wipes along the deflected or receding surface 1" in the spindle, to assume a substantially sheathed position in the latter. In this relation of the parts it will be seen that the filling package may be applied or removed substantially unobstructedly.

The shuttle is provided with the usual in set metallic plates or cheeks a which afford supports for the pin 0 and are formed with hooks o which, if the core of the package is a quill having an annular groove at its butt, engage in said groove when the spindle is depressed. The shuttle has the usual stop to limit the downward movement of the spindle, in the present case being a pin w. This pin is usually fitted at its ends in the walls of the shuttle which, being of wood, break away when, as often occurs, too much pressure downwardly is exerted on the spindle in depressing it. In the present instance, I mount said pin in the checks or plates at, as shown, recessing the under side of the spindle butt, as at 00, so as to allow the spindle to descend to its proper limit. This gives a much stronger construction, as will be obvious.

Ha ing thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In combination, a shuttle body having a cavity for the filling package and an axial supporting and gripping means for said package consisting of a spindle housed in said cavity and pivotally movable in the shuttle body into projecting relation thereto, and an elongated elastic member secured at one end in the shuttle body at a point near to but remov d from the spindle pivoting axis and extending toward the free end of and resiliently held against the spindle and lying in the plane of movement of the spin dle, substantially as described.

2. In combination, a shuttle body having a cavity for the filling package and an axial supporting and gripping means for said package consisting of a spindle housed in said cavity and pivotally movable in the shuttle body into projecting relation thereto, and an elongated elastic member secured at one end in the shuttle body at a point near to but removed from the spindle pivoting axis and extending toward the free end of the spindle, the other end of said member being rebent and resiliently held against the spindle and lying in the plane of movement of said spindle, substantially as described.

3. In combination, a shuttle body having a cavity for the filling package and an axial supporting and gripping means for said package consisting of a spindle housed in said cavity and pivotally movable in the shuttle body into projecting relation thereto, and an elongated elastic member secured at one end on the shuttle body at a point near to but removed from the spindle pivoting axis and extending toward the free end of the spindle, the other end of said memher being rebent and resiliently held against the spindle and lying in the plane of movement of said spindle and said spindle having a longitudinal groove receiving said other end, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.
